87-15: The Growth and Control of Nitrifying Bacteria in a Urea Plant CoolingA urea plant cooling water system experienced problems with the growth of nitrifying bacteria which produced nitric acid from ammonia resulting in a sharp drop in the pH of the cooling water was found to drop from 7. 5 to 6. 1 over a period of 34 days. It was demonstrated in the laboratory that bacteria possessing the enzyme urease were present in the cooling water. A number of biocides were screened for their ability to inhibit growth of ammonia

and short and long term accountability for performance in vendor/user partnership after bid has been awarded

(2) Plan to improve

This code specifies the procedures

The objective of the Task Group on the Use of High Dissolved Solids Waters in Cooling Towers is the preparation of guidelines summarizing the best available information on 1) selection of materials for cooling tower water system construction

produces a real hazard

This paper considers important aspects of designing seawater cooling systems

The keys to measuring the effectiveness of any biocide program are the ability to quickly and accurately measure the microbiological activity in the cooling system

Summary White Paper

lubricating oils in steel mills and other oil-based process leaks all contribute to the above-mentioned problems

and still is the dominant material

technological progress and new scientific knowledge

with varying water qualities
